摘要
明清时期萧绍平原的环境变迁与水利工程紧密相关。起初,萧绍平原北部的西小江由于受到湖泊围垦与钱塘江改道的影响,上游洪水无法宣泄,下游泥沙淤积且受海潮顶托,致使西小江河道淤塞水患频仍,因此排泄上游洪水与遏制下游海潮成为治理西小江的主要任务。明中叶以来的浦阳江改道、三江闸以及相关配套水利工程的兴筑与修缮缓解了西小江的水患灾害,趋于合理的水利设施结构有利于之后区域环境和经济较长时期的安定。同时,人们改造水环境的多重效果也显示了传统社会的条件下人在与自然互动过程中的张力及其限制。
Environmental changes taking place in the Xiaoshao Plain in Ming and Qing was closely related to the irrigation works.Due to the effort to cultivate more wastelands by enclosing lakes and the fact the River Qiantang changed its original course,the upper reaches of the River Xixiao could not be used to discharge floods.At the same time,the River's flood risk increased on the grounds that the silt in the lower reaches was constantly pushed back by the sea tide.Thus,the work taming the River focused almost exclusively on the flood discharge and tide controls.Since the mid-Ming,several water conservancy projects substantially reduced the flood risk,as well as greatly contributing to the stable environment and the prosperous economy in this region.
